Answer:
Tahiya attempted 3 incorrect answers.
Helmin attempted 11 incorrect answers.
Step-by-step explanation:
Correct = +4
Incorrect = -3
1) Tahiya got 12 correct answers and scored a 40, the number of incorrect answers was:

2) Helmin got 5 correct answers and scored a -14, the number of incorrect answers was:

In both cases the number of incorrect answers obtained is a fraction, which means that either the data provided is inaccurate, or that the scores obtained by the students are approximate. Let's round the number of incorrect answers to the nearest whole answer.
Tahiya attempted 3 incorrect answers.
Helmin attempted 11 incorrect answers.
D. Similar SSS similarity triangle TLM
Simplifies to:
1.690196x+396.139706=2
Let's solve your equation step-by-step.
1.690196x+396.139706=2
Step 1: Subtract 396.139706 from both sides.
1.690196x+396.139706-396.139706=2-396.139706
1.690196x=-394.139706
Step 2: Divide both sides by 1.690196.
1.690196x/1.690196 -394.139706/1.690196
x= -233.191716
Answer: x= -233.191716
Remember to use trig form the general equation is: r(cos(angle) + i sin(angle))
to find r, take √a^2 + b^2 to get 3 for the angle it would be undefined so thee argument would be π / 2. So your answer is 3(cos(π/2) + i sin(π/2))
